ath9k driver issue after installing virtualbox4.1.12

[Sasa Paporovic]

I am on Ubuntu12.04 64bit updated to 14.4.2012

An simple installation of virtualbox 4.1.12 causes ath9k driver problems.

The speed of the wireless internetconnectin is dropping <100kbit from 700kbit at maximum.

This change is permanent.

I have also reported this a longer time ago to opensuse bugtracker.

---------------------------------------------------------------
On opensuse was no bughandling on this.

On virtualbox bugtracker they do not beliefe that this is a conclusive bug.

I´ve switched from kernel head kernel-desktop-3.0.0-4.1.x86_64 to kernel kernel-desktop-3.0.0-38.1.x86_64 from tumbleweed, which causes some problmes.
Virtalbox(the ..38.1 module for VB4.1 was also installed) was not able to start any guest and I get a break in my internet connection after some minutes(ath9k for my TPLINK),, so whatever you´ve done to kernel-desktop-3.0.0-38.1.x86_64 it is not recommend.
I´ve switched back(multi kernel system) to kernel-desktop-3.0.0-4.1.x86_64 and all worls again very smooth.

Some logs will be attached, when you missing something, please contact me.

Sorry, virtualbox is not supported with tumbleweed.

Regarding ath9k issue. Could you attach (uncompressed) dmesg output?

[Sasa Paporovic (melchiaros)]

I attach dmesg output the next time I have a crashed network.-> I´am on kernel 3.0.0-10 now, which works better than ...the original reported here.-> But htere are still problems.

I am now on kernel 3.0.3-41 default.But it is the same with every kernel.

Ok, thanks. It's clear now what it does:
ath: Unable to reset channel (2462 MHz), reset status -5
ath: Unable to reset channel (2462 MHz), reset status -5
ath: Could not kill baseband RX
ath: Unable to reset channel (2412 MHz), reset status -5

It's still unclear to me why it happens though.

[Sasa Paporovic (melchiaros)]

o.K,
I´ve prevent myself until now(and would like to do it further),
but would it help to do something from this stuff:

http://linuxwireless.org/en/users/Drivers/ath9k/debug

If yes or you have some other stuff in mind, can you give me a workflow for what to do?

[Sasa Paporovic (melchiaros)]

I´ve also sometimes problems on sytem start - no network

Ideally, if you could reproduce with kernel-vanilla:
http://download.opensuse.org/repositories/Kernel:/vanilla/standard/
and report to upstream developers either via bugzill.kernel.org (after kernel.org is turned back to life) or directly via atheros list: <email address hidden>

Closed due to lack of response.

[Sasa Paporovic (melchiaros)]

Oh, have not recognized that you have closed this.

I have had time today to do it and the technikal equipment -> for several month I could not install openSUSE.

[Sasa Paporovic (melchiaros)]

This bug is back on openSUSE12.1 with kernel 3.1.0 in full hight, like it was on kernel 2.37.1 or 2.37.6. -> Very bad.

------------------------------------------------------------------------------

So what I´ve done is to set debugging for ath9k on in openSUSE 12.1 with /usr/scr/linux ~ make menuconfig

like it is described on :

http://linuxwireless.org/en/users/Drivers/ath9k/debug

-------------------------------------------------------------------------------

It was catastrophic for my wireless connection -> after a newstart with vanilla kernel3.1.0 wireless connection breaks completely on start.

-------------------------------------------------------------------------------

Another newstart with desktop kernel3.1.0 has the same consequences.->no wireless on start.

-------------------------------------------------------------------------------

I would like to keep it on this bugtacker for now until it is a little bit more clearer what it could be -> hope this is o.k for you.

[Sasa Paporovic (melchiaros)]

Ahaha,
I´ve located it, well ... better.

I´ve installed openSUSE12.1 now for several times.

In principle this bug is a bug for ath9k by itself, because it is unstable also on fedora15, fedora16, ubuntu11.4 and ubuntu11.10(I´ve all seen an bare hardware) and -this is the point- without virtualbox installations!

BUT: When I do virtulabox installations(don´t know why I did not see that before!?), the stability of ath9k decreases dramatically, such to a state were wireless network is useless.

[Sasa Paporovic (melchiaros)]

The think is:

It´s mostly up to virtualbox developers to handle this, because they have old hard bugs there which affect also the windows platform. This shows that it is a problem which their network implementation and not so of any kernel.

Beside of this also the kernel should not allow a program to corrupt the whole network.

[Sasa Paporovic (melchiaros)]

Any suggestions? I´am standing a bit in the rain with this.

I'm boot new liveDVD Kubuntu, wifi work no problem.

[Ciro-iriarte (ciro-iriarte)]

ath9k behaves better after upgrading to kernel 3.x from stock kernel in OS 11.4. After resuming laptop it stops working, but it's usable after "modprobe -r ath9k" and "modprobe ath9k"

[Megavolte (megavolte)]

I'm upgrade opensuse 11.4 to 12.1 kernel 3.1. Wifi works, but after some time usb wifi adapter is disabled. I have to take out and insert it again.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Is this wifi module a USB gadget ?

[Megavolte (megavolte)]

Yes.

[petar (petars-70)]

This is problem of driver or firmware or hardware device. I have TL-WN722N and have same terrible experience. I used it as AP on debian 6. After problem tried latest hostapd and latest compat-wireless(self compiled) but no luck. Looks like tplink have problem with wifi devices because their router(1043) loosing wifi conection too after about 24 hours.

[petar (petars-70)]

message that i get when wifi stops: ath: phy1: unable to remove station entry for: <mac address removed>

and with DWA-140 no problem after 2 weeks work but range is worst

[Machen-i (machen-i)]

Sorry for very late response. I've recently got a Atheros USB module to test. This one is working fine to me with the kernel v3.8, ath9k_htc.

So I don't see the issue happen to me. Would you like to duplicate it for me. I'd like to see what to dig. :)

[Jcheung (jcheung)]

Hi Evgeny, since openSUSE 12.3 is out, can you retest on the latest version to see if problem still exist or not ?

[Jcheung (jcheung)]

I closed for noresponse as no update from user since comment#25 for almost a year.

openSUSE 12.3 is out and kernel version is 3.7, please test on latest version and fire a new bugzilla then.
